... In this class I would like for you to develop a “quantum worldview” – by which I mean that I would like to re-examine some of the concepts that you have previously, in classes like classical mechanics and electricity and magnetism, held as starting assumptions. In doing this, you will need to learn ...

Quantum Mechanics is Real Black Magic Calculus

The more you see how strangely Nature behaves, the harder it is to make a model that explains how even the s ...
